Keypad Function
Units
Selects the displayed unit of measure, e.g., lbf, kgf and N.
When using the Units button, you can only switch between specific units
depending on the unit used when programming the instrument.
The units in correlation are: (lbf, kgf, N), (kN, klb), (ozf, gf)
Peak
Selects the peak hold display mode of the instrument, e.g., live data, positive
peak, and negative peak. (This function must first be enabled using the F36
parameter)
Zero
Zeroes the force display reading.
Data
Sends the displayed data to the serial communication port.
On/Off
Press and hold for a few seconds to turn the instrument ON. Press and hold for
about five seconds to shut the instrument OFF.

Installation & Overview
Remember that the installer is ultimately responsible to assure that a particular
installation will be and remain safe and operable under the specific conditions
encountered.
The instrument must be properly configured and calibrated prior to use.
Installation
Find a suitable location for the instrument and use the included bracket to mount the unit to a wall or
table. Use this handy guide for mounting the bracket to a wall or table:
The INSTRUMENT ships with a force sensor cable which plugs into the appropriate connector. Use the
following color codes to connect the force sensor.

The INSTRUMENT features one full duplex RS-232 serial port, designed for connection to a computer or
a serial printer. The same port may be also used as a simplex, RS-232 port designed for connection to a
remote display.

Ground
When using batteries to power the instrument, it requires 4-AA batteries to operate (not included). To
install the batteries, remove the plastic battery cover from the rear panel. Observe proper direction
(polarity) of the batteries. Replace the battery cover.
The INSTRUMENT may also be powered by the included AC wall adaptor.
Getting Started
1. Press and hold the ON/OFF key on the instrument for two seconds.
After a brief initialization period, the instrument will revert to a zero (“0”) force display.
Your instrument is now ready for configuration and calibration.

Instrument Configuration
Configuration Menus
The G501F contains three menus to configure the instrument:
Setup (“F”) Menu –Configures all metrologically-related parameters including calibration procedures.
User (“A”) Menu –Configures COM2 communication parameters and other misc. parameters, e.g.,
automatic turn off.
COM1 (“C”) Menu –Configures COM1 communication parameters.
The configuration menus are laid out in the following vertical arrangement:
•Top [Menu selection] level
•Parameter level
•Selection level (or function level, e.g., span calibration)
Please review the following chart to get a feel for how to navigate among the various menus and
parameters.

Entering the Setup (“F”) Configuration Menu
1. Switch off the instrument by pressing and holding down the ON/OFF key for about 5 seconds.
2. Press and hold down the ON/OFF key (about 20 seconds) until the screen shows
“-F-”.
3. Scroll down using the PEAK (down) key to reach the parameter level. The instrument shows “F 1”.
4. Move from one “F” menu parameter to the next by using the DATA (left) or ON/OFF (right) keys. For
example, to go from F1 to F2, press the ON/OFF key. To go from F2 back to F1, press the DATA key.

5. Once you have arrived at the proper “F” menu parameter, e.g.,” F 1”, press the
PEAK (down) key once to arrive at the selection level. The instrument displays the current parameter
setting.
6. If there is a selection list, scroll thru the available parameter settings, use the DATA (left) or ON/OFF
(right) keys. Otherwise, use the arrow keys to adjust the displayed value to the new value.
7. Once the setting you want is displayed on the screen, press the ZERO (set) key to save this value and
revert up to the parameter level, e.g.,” F 1”.
To save all parameter settings, it is imperative to exit all menus in the following manner: At the parameter
level, press the UNITS (up) key twice (two times) to exit the Setup Menu. The instrument displays ‘SET’
and then automatically powers off.
